Please help debug this lab! Please!

Hey Guys,
Its me..yet again! However, this time I have nearly finished my lab but need help with some debugging. It would be so so appreciated.. Thank you in advance..It starts off with what is required off the lab and then the program itself.
Hope you guys can help. Thanks
Mack

** Lab 4 Pointer Applications 20 Points

*************************************************

Write a program that reads the size of an array from the keyboard.
The array is to be dynamically allocated in the heap.
Then the program reads integers from the keyboard into the array.

Modify the straight insertion sort from Chapter 8 so that it sorts
the array into ascending and descending order.

The program must not change the original array. Do not create any other
integer arrays. (See figure 10-25, page 515).

Print the sorted arrays and the original array to a file, using the
following format:

========== =========== ============
ORIGINAL ASCENDING DESCENDING
========== =========== ============
50 20 100
70 50 70
20 50 70
100 70 70
70 70 50
50 70 50
70 100 20

Finally, determine and print the frequency histogram to screen,
as it is shown below:

20: 1 *
50: 2 **
70: 3 ***
100: 1 *

Data : Run your program twice:

Test Data Set 1:

10 here you enter the size of the array
10 10 30 30 40 50 50 50 60 60


Test Data Set 2:

25
50 30 10 90 5 20 25 90 40 35 50 30 50 30 90 5 40 50 90 30 10 5 20 10 35

NOTE: Use pointer notation throughout. Do not use an index to access the
elements in the array: use a pointer, as in the following example:
__________________________________________________ __________________
YES

int ary[10] = {10, 15, 10, 30, 40, 50, 60, 70, 80, 90 };

int *pWalk;
int *pLast;

pLast = ary + 10 - 1;
for( pWalk = ary; pWalk <= pLast; pWalk++ )
printf( "%3d", *pWalk );

__________________________________________________ ___________________
NO

int ary[10] = {10, 15, 10, 30, 40, 50, 60, 70, 80, 90 };

int i;

for( i = 0; i < 10; i++ )
printf( "%3d", *(ary + i) );
